"Okay, fine. According the mirror, whose name is Jack, it's a segue."

"A segue?" When Diana nodded, her expression making it clear she wasn't kidding around, the older Keeper ran a hand up through her hair. "I have a sudden need for profanity."

"Yeah. That was my reaction. That mall's got to cover at least four acres. Maybe as much as six."

"Segue?" Dean asked, dragging his chair around far enough to see Claire's face.

"A metaphysical overlap intended to displace reality."

He switched his attention to Diana.

She scratched thoughtfully at her left elbow and tried to come up with an explanation he could understand. "You know how the Otherside is neither here nor there? That everyone, good guys, bad guys, the Swiss, can all get in but can only get back out into their own reality, the one they left from? Well, in a segue, someone, or something, matches up a piece of the Otherside to this reality and blends them together until enough of the copy occupies the s.p.a.ce of the original whereupon the copy takes over. That puts a piece of the Otherside inside this reality so that anyone can enter it from their reality and exit here. The Erlking Emporium is anchoring the biggest segue I've ever heard of."

"The biggest?"

"Well, you can't count Las Vegas, that's a metaphysical heritage site. All that bad taste in one place put a real strain on reality."

It took Dean about half a heartbeat to decide that was one of those comments he didn't need to understand. "But how did the segue in the mall get so big without you guys noticing?"

"h.e.l.l," Austin answered before either Keeper could.

He put his front paws up on Claire's knee and she lifted him onto her lap. "They hid a smaller bad inside the noise of the biggest bad. They probably set the anchor last fall while we were closing the hole and after that, it was just a matter of keeping things moving ahead, slow and steady."

"And they are?"

"Your guess is as good as mine. Oh, wait. No it isn't." He paused and licked at the quarter-sized bit of black fur on his front leg. "For simplicity's sake, let's just call them the bad guys."

"But the Otherside isn't necessarily bad."

"Doesn't matter; with a segue anything can cross over. Bad, good . . ."

"Hey!" Sam protested, coming out of the kitchen. "This world could use a little more good in it. I ought to know."

Austin sighed. "Yeah, yeah. Light. Angel. Cat. Yadda. We all know the story and you're missing the point. A little good is fine. A lot of good isn't."

"Keepers maintain the balance, Sam. A functional segue could tip it in either direction, and if they're using trolls, well, I'm guessing we're not heading for hugs and cheesecake." Claire rubbed her thumb gently over the velvet fur between Austin's ears. "Shutting them down is a tricky business," she added thoughtfully. "It can't be done from this side; I'll have to cross over and go to the source."

Diana rolled her eyes. "You'll have to? Try we'll have to. If I can't close something this big on my own, you certainly can't, Basic Folklore 101, the younger sibling is always more powerful. I have the power, you have the experience. United we stand, divided we fall, yadda yadda. So I suggest you get over yourself, drop the whole I'm-the-only-one-who-can-save-the-world c.r.a.p, and recognize that we've got trouble."

"Right here in River City," Sam added.

"Show tunes?" Austin glared down at the orange cat. "You have got to be kidding."

"I have three words for you, Austin." Diana leaned a little closer to Claire's lap and flicked up a finger for each word. "Andrew Lloyd Webber. But that's so not what we're talking about. We need to get back into that mall and close that segue. It's going to take some time, so I suggest we start tonight."

"Ignoring your less than flattering opinion of my character," Claire muttered darkly, "I agree."

"I don't."

"Listen much, Dean? Segue bad. Keepers good. And I don't know where I was going with that, but the sooner we get the sucker closed down the better."

"Not arguing," Dean told the young Keeper calmly. "You said it's going to take some time, that means you'll be there for a while?"

Diana shrugged. "Yeah, but . . ."

"So you can't just rush in all unprepared."

"I guess not."

"You'll have to pack."

Claire twisted around until she could see his face. "We have everything here . . ."

"It'll still take time." He glanced over at the old school clock hanging on the wall in the kitchen. "It's past eleven now. It'll be close to midnight when you're ready to leave. By the time you get to the mall, you've both already been up for what, sixteen, seventeen hours? You'll be facing whoever created this thing when you're tired. You won't be thinking as quickly or as clearly. The bad guys could win before you even get started and then where's the world? Up sh . . . the creek without a paddle." Taking a deep breath, he let it out slowly, holding Claire's gaze with his, lacing the fingers of his right hand through the fingers of her left. "You've got to weigh the delay against going in tired and unprepared. You should sleep tonight and go in tomorrow morning."

Diana opened her mouth to deliver a blistering reply, and snapped it shut again as Austin said, "He's right."

"He's a Bystander!"

"And I'm a cat, so listen up." He climbed from Claire's lap up onto the table, leaving sweaty paw prints on the polished wood. "Going in tired and unprepared is a good way to get our collective b.u.t.ts kicked but, more importantly, going in tonight gives the advantage to the other side."

"You mean the Otherside?" Diana sniped.

"Don't interrupt. Two Keepers and two cats head into an empty mall in the middle of the night and we might as well call first to tell them we're coming. There's no way even the most idiotic, written for television, evil overlord isn't going to notice something like that. The moment we cross over, BAM! And that's if we're lucky. We all know there's a whole lot worse than BAM waiting out there."

"No, we don't." Ears saddled, Sam sat down on Diana's foot. "What's worse than BAM?"

"Splat. Crunch. Grind. Chew." When no one seemed inclined to argue, Austin continued. "We get a good night's sleep and go in tomorrow morning with all the other shoppers, hiding in plain sight. We slip across with no one the wiser, you two close down the segue, and we're home by lunch."

"Lunch?"

Austin snorted. "Okay, it's a metaphorical lunch some days in the future."

"Look, it's my Summons," Diana protested, tumbling Sam off her foot and jerking her chair away from the table. She had a strong suspicion that had come out sounding whinier than she'd intended.

"You came here for help," Claire reminded her. "You were there, in the mall; is there a chance the copy will be matched up before morning?"

"No. But . . ."

"Then I vote we wait. But you're right." She raised the hand not holding Dean's in surrender. "It's your Summons. Only you can make the final decision."

"Don't patronize me."

"Then stop acting so childish. When you got here, you were willing to stop for a sandwich, and now you're set on charging in where angels fear to tread."

"Angels don't fear much," Sam began, caught sight of Austin's expression, and decided he'd rather be under the table.

Diana folded her arms and just managed to stop her lip from curling. Knowing they were right didn't help. "All right, fine. We'll go in the morning."
